摘要
采用水浴超声自燃法制备了Cd0.35Zn0.65Ce0.03Fe1.97O4 (CZCF)/石墨烯纳米片复合材料。x射线衍射（XRD）证实了该晶体为立方尖晶石相，晶格常数在8.422 ~ 8.731 Å之间。晶粒尺寸由20.3 nm增大到34 nm。拉曼分析证实了尖晶石相的特征振动模式的存在，并且在~ 1320 cm - 1和~ 1582 cm - 1的附加d波段的出现也证实了GNPs的存在。形貌分析表明，GNPs的加入使其形状不规则，团聚度增加。电阻率研究证实了CZCF/GNPs复合材料的半导体性能。切线损耗随频率的增加而减小，其中CZCF/5wt%GNPs复合材料的切线损耗最小。饱和磁化强度（MS）随GNPs添加量的变化显著，对于CZCF/5wt%GNPs样品，MS最大值为36.84 emu g−1。剩余磁化率（Mr）和方度比（SQ）呈非线性变化，表明磁畴结构发生了变化。随着GNPs的加入，矫顽力（HC）开始下降，在5wt%GNPs时，矫顽力最小为33.32 Oe，表明其具有软磁性质。这些结果表明，通过GNPs集成，基于CZCF SFs的复合材料具有可调性，这使它们成为潜在应用的有吸引力的候选材料。
Facile synthesis of Cd0.35Zn0.65Ce0.03Fe1.97O4/GNPs composites and their magneto-dielectric response
The Cd0.35Zn0.65Ce0.03Fe1.97O4 (CZCF)/Graphene nanoplatelets (GNPs) composites were synthesized using a self-combustion method by following the bath sonication. A cubic spinel phase was confirmed by X-ray diffraction (XRD), and the lattice constant lies within the range of 8.422–8.731 Å. The crystallite size was increased from 20.3 to 34 nm. Raman analysis confirmed the existence of characteristic vibrational modes of the spinel phase, and the presence of GNPs was also confirmed by the appearance of additional D-band at ~ 1320 cm⁻1 and G-band at ~ 1582 cm⁻1. Morphological analysis shows the irregular shape and increased agglomeration with the addition of GNPs. The electrical resistivity study demonstrated semiconductor behavior of CZCF/GNPs composites. The tangent loss decreased with increasing frequency, and the CZCF/5wt%GNPs composite has the minimum tangent loss. The saturation magnetization (MS) varied significantly with GNPs addition, and has a maximum of 36.84 emu g−1 for the CZCF/5wt%GNPs sample. The remanent magnetization (Mr) and squareness ratio (SQ) showed non-linear behavior, indicating changes in magnetic domain structure. The coercivity (HC) decreased initially with GNPs addition and has a minimum of 33.32 Oe at 5wt%GNPs, suggesting a soft magnetic nature. These results demonstrate the tunability of composites based on CZCF SFs through GNPs integration, which makes them an attractive candidate for potential applications.
期刊介绍：
The Journal of Materials Science: Materials in Electronics is an established refereed companion to the Journal of Materials Science. It publishes papers on materials and their applications in modern electronics, covering the ground between fundamental science, such as semiconductor physics, and work concerned specifically with applications.
